# Hutter Eigenmass Transfer Plan

Status: `TRANSFER_PROTOCOL_HOLD_HUTTER_CLAIM`

Decision: `ADMIT_TRANSFER_PROTOCOL_HOLD_HUTTER_CLAIM`

This document ports the DESI/MaNGA multiscale eigenmass pattern into the Hutter
compression lane as a tuning protocol. It is a method-transfer receipt, not a
compression benchmark.

Claim boundary: no enwik9 run, no compression-gain claim, no Hutter Prize claim,
and no FPGA/ASIC promotion is made here.

## Imported Signal

```text
DESI/MaNGA tracer cosine:       0.702922832
DESI/MaNGA sharpening factor:   1.784206501
```

Only the evidence-sharpening pattern transfers. Astronomy values do not become
compression scores.

## Hutter Feature Basis After Tuning

- `byte_offset_phase`
- `symbol_class`
- `local_context_hash_class`
- `long_range_recurrence_distance`
- `prediction_cache_hit`
- `ram_trace_reuse`
- `residual_entropy_proxy`
- `oisc_instruction_density`
- `ammr_receipt_depth`
- `replay_delta_cost`

## Transfer Ladder

- DESI `literal row surface` -> Hutter `raw corpus windows`; gate `WINDOW_FIXTURE_ONLY_UNTIL_CANONICAL_ENWIK9`
- DESI `joined gas/shock constrained cells` -> Hutter `byte-exact replay fixtures constrained by Rust OISC closure`; gate `LEAN_RUST_REPLAY_REQUIRED`
- DESI `constraint sharpening factor` -> Hutter `compression candidate must sharpen prediction/replay axes without losing byte-exact closure`; gate `SHARPENING_WITH_EXACT_REPLAY_ONLY`
- DESI `multiscale cosine alignment` -> Hutter `candidate feature direction must align across raw windows, token/logogram windows, and OISC replay receipts`; gate `MULTISCALE_ALIGNMENT_BEFORE_PROMOTION`

## JPEG XL Starfield First Sweep

Add a non-claim visual sidecar:

```text
Hutter text fixture
  -> byte/window projection
  -> JPEG XL sidecar image
  -> pixel-density pattern collections
  -> eigenprobe over density groups
  -> "grouped stars" observation receipt
```

This is not a classifier and not a compression claim. It only asks whether a
projected pixel-density field shows grouped starfield-like patches worth
returning to the byte fixture for replay checks.

Allowed decisions:

```text
OBSERVE_GROUPING
OBSERVE_NO_GROUPING
HOLD_PROJECTION_NOISE
QUARANTINE_MISSING_PROVENANCE
```
